NASA Connect - AO - Observatories



Second segment of NASA Connect Ancient Observatories explaining how the height of the sun relates to the growing seasons and the length of daylight. This segment describes how Ancient Egyptian and Greek cultures used astronomy in their lives. The segment also contains an activity for exploring how a gnomon works. In the activity students must track the shadows made by a gnomon in 30 minute intervals. The activity will teach students how the length of the shadows and the angles created by the gnomon are related to the position of the sun.
